Abstract

Apparatus for collecting refuse and loading the refuse onto a side-loading, refuse collection vehicle having a bed and a loading compartment with a top opening aperture therein, characterized by: a trash container that includes a sloping front wall for dumping the trash from the container when it is inverted, doors, loading hooks, and a pair of arcuate track engaging means for maintaining the container in place when it is inverted onto the bed of the vehicle and preventing escape of trash; a pair of arcuate tracks mounted on the vehicle; a base connected to the front of the bed of the vheicle so as to accommodate lateral motion of a pick up arm; and an extensible and retractable L-shaped cantilever pick up arm for being moved outwardly to pick up, invert, and lower the trash container by its hooks responsive to operation of the controls by only a driver of the vehicle, without requiring rolling of the container into position by a helper. Also disclosed are preferred structural embodiments, including safety catches and the like.

Claims

1. A trash container for receiving refuse and for use with a side pick up refuse collection vehicle comprising:

a. a bottom;

b. rear wall and side walls having adjacent ends connected together and connected with said bottom and extending upwardly therefrom to define a body;

c. a top connected with said rear wall and said side walls;

d. a front wall connected with said bottom and said side walls so as to form an obtuse angle with said bottom such that refuse will be dumped from said container when it is lifted and inverted through an angle Alpha of greater than 90* and less than 180*;

e. upper front door hingedly connected with said top by a first hinge;

said upper front door adapted to hang in a normal closed position by gravity and adapted to be swung inwardly manually for deposition of said refuse and to be swung outwardly by the force of gravity when said container is lifted and inverted through said angle Alpha ;

f. lower front door hingedly connected with said front wall by a second hinge and adapted to be swung outwardly open by the force of gravity when said container is lifted and inverted through said angle Alpha and to be swung closed when said container is uprighted from its inverted and dump position;

said lower front door being normally inclined inwardly from its bottom to its top in its closed position so as to prevent influx of rainwater into said container when left outdoors;

g. a pair of loading hooks mounted on the top of said container;

said loading hooks being disposed and spaced apart a sufficient distance that the front to rear vertical plane of the center of gravity of said container is located therebetween;

said loading hooks having an opening readily accessible from the front to facilitate attachment of a lifting arm; and

h. a pair of arcuate track engaging means for engaging a pair of tracks on said vehicle during said lifting and inverting of said container;

said track engaging means being disposed one on each side of said front door such that said container is properly inverted and emptied regardless of whether the operation is carried out on level terrain or not, i. said arcuate tracks haing respective terminal portions at their top ends adjacent said first hinge and at their bottom ends adjacent said second hinge; and

j. stop means to limit the swing of said lower front door in its closed position.

2. The trash container of claim 1 wherein said loading hooks each have a safety catch for retention of a lifting arm therewithin when said container is lifted and inverted during dumping.
